Tire tread



FIG. 1 is a perspective view of the tire tread of my design;

FIG. 2 is a front elevation view of the tire tread of my design;

FIG. 3 is a side elevation view of the tire tread of my design;

FIG. 4 is a side elevation view of the tire tread of my design, taken from the opposite side of that shown in FIG. 3; and,

FIG. 5 is an enlarged, partial view of the tire tread of FIG. 1, as indicated by the break lines.

In the drawings, the broken line disclosure depicting the sidewall and inner bead depicts environmental subject matter and forms no part of the claimed design. The broken line at the transition between the unclaimed sidewall and the claimed tire tread identifies the peripheral boundary of the claim. 

CLAIM The ornamental design for a tire tread, as shown and described.
